Application filed July 6, 1920. Serial No. 394,195.

To aZZ "(11720171 it may concern:

Be it known that 1. PAUL J. HUEBER. o Syracuse, in the county ofOnondaga, in the State of New York, have invented new and usefulimprovements in Concrete-Building Forms. of which the following, takenin connection with the accompanying drawings, is a full. clear, andexact description.

This invention relates to temporary forms for concrete buildingstructures and to the method of erecting the same. the main object beingto provide a system of correlated "form sections which may be easily andeXpedi-: tiously erected or assembled in a secure manner for receivingplastic concrete for walls, columns. floors and various other partsduring progressive building.

In other words. I have sought to provide a system of terms capable ofbeing assembled in many different combinations for producingall-concrete buildings of widely varying designs.

Another object is to render the assembled form sections substantiallyself-sustaining during the process of erection and filling in of theconcrete.

A turther object is to enable the form sections to be easily andsystematically removed and reused in the construction of other con.crete buildings without material loss from deterioration or breakage.

Other objects and uses relating to specific devices oi. certain tormsections will be brought out in the following description.

In the drawings:

The method of erecting the forms for the various parts of the building,briefly stated, consists-- First, in laying a suitable concretefoundation or footing course to the desired level and permanentlyanchoring therein at predetermined intervals throughout the ing to thewidth of the spacing blocks.

Fourth, securing a temporary stiffening frame to the upper portions ofthe several interior studs and bracing the column form tosaid studs.

Fifth, attaching temporary girder forms 'to and betweenthe studs andcolumn forms, and

Sixth, placing the temporary wall and floorpanels in operative positionandsecuring them to their respective studs, girders and columns, afterwhich the spacing blocks, wall studs, girders "and panels for thewallsa11cl'fioo1*s"-1i1ay be continued indefinitely for successive stories Iwith such alterations as may be necessary for modified detailsofconstruction; it being understood that the foregoing is intended onlyas a briefstatement of the general plan of erection of the forms and notas a specific method of assembly,- which will be hereinafter more fullydescribed.

Foundation.

In carrying out the' objects stated, a. con- "crete foundation orfooting course -l is firstlaid w1thout forms in a trench, as

A, which is made to the desired dimensions and extended under the entirewall with its upper face substantially horizontal orlevel to receiveandsupport the concrete superstructure and also the temporary formstherefor, as will be hereinafter more fully described.

A series of previously formed concrete" spacing blocks 2 (Fig. 6) areplaced at suitable intervals alongand upon the longitudinal centers ofthe upper faces of the footlngcourse 1 and are of considerably lesswidth thanthat of the footing course,

' or substantiallvthe same width as the width or transverse thickness ofthe concrete wall which is to be erected upon the footing course, eachspacing block having incorporatedt herein a U-shaped anchor bolt--ahaving its opposite arms protruding below. the lower face of theblock, as shown in Fig.

G--: and embedded in the footing course -1, while the latter is in amore or less plastic state for firmly holdingthe block in a fixed andpermanent position on the footing course, said block being also providedwith a transverse bolt opening --a forn'eceiving aclainpingboltpresentlydescribed by which certain temporary form sections3- are clamped in place.

These form sections 3- preferably consist of metal faced wooden stripsrunning lengthwise of and upon the upper face of the footing course 1and clamped against the opposite side faces of the blocks -2 by means ofbolts 4 which are passed through the bolt opening a'- in the blocks -2-and also through registering apertures in the base plates or strips 3-,as shown more clearly in Figure 5- each bolt having one end providedwith a head for engaging the inner face of one of the strips, while theopposite end is provided with a diametrical slot for receiving a wedge-5 for engaging the outer face of the opposite strip and thereby firmlylock ing the base plates or strips -3 to the separators preparatory toerecting other form sections, it being understood that the bolt openingsin the separator blocks 2 and form sections 3 are sufliciently large topermit the bolts -a to be easily inserted and withdrawn when the lockingkeys 5 are removed.

These base plates or strips 3- may be of anysuitable length convenientforhandling, but preferably terminate at one orthe other of thespacingblocks -2- so'that their adjacent ends may be clamped against thespacing block by the same clamping-bolt "-4 and wedge 5, the meetingends of the sections --3-being rabbeted and beveled as shown in Fig. 5-to permit them to overlap one upon the other and to be readily placed inoperative position and removed when the bolts 4:- are withdrawn, theoverlapping ends of one or more sections serving also to assist to holdthe adjacent sections in place as shown more clearly in Figure 5.

Additional clamping bolts 6 (Fig. 11)

are inserted in registering openings inthe oppositestrips 3 somedistance from and between the bolts -4L or spacing blocks -2- forholding the lower ends of interior and exterior stud sections 8- inoperative position upon the correspondingstrips or base plates, as shownmore clearly in Figures 2()- and 21; the inner ends of said bolts -6being provided with clownwardly offset ends -6- seated in recesseswholly within the adjacent faces of the strips 3, while their oppositeends are slotted to receive wedge shaped keys -bfor engaging theadjacent faces of the studs =-8 and strips -'-3--, as shown more clearlyin Figures 20- 'and 21, thereby firmly locking the studs to the strips.

The upper'outer corners and upper'inner corners of the'exterior andinterior strips -3, respectively, are abbeted longitudinally, and'theirupper faces beveled in opposite directions to receive the lower edges ofthe stud sections --8 and 9- and suitable panel sections hereinafterdescribed, said lower edges of the stud sections ,and

panel sections being similarly rabbeted and beveled to permit saidsections to be easily removed and replaced from and upon theirrespective strips -3 when the locking keys b are removed, the loweredges of the studs being recessed to receive portions of the bolts 6, asshown more'clearly in Figure 21 and are reinforced by a metal wearingplate Z) for engagementby the key Z).

In practice the interior footing plate-3- is preferably laid upon theupper face of the footing course ,1 before the latter is set and beforethe spacing blocks 2 are placed in operative position so that the lattermay be correctly alined against the interior plate lengthwise of thefooting course in anchoring the same thereto, after which the exteriorfooting plate 3' isplaced in opthe adjacent faces of the spacing blocks.

The spacing blocks 2- determine the amount of separationor space, as 7-,be-

' tween the wall studs and also between the wall panels hereinafterdescribed, and, there fore, determine the thickness of the concrete wallwhich is to be progressively erected between the wall studs and betweenthe panels.

' .WaZZ studs,

I preferably employ one set of studs, as S for the interior wall formand another set, as -9 for the exterior wall form, and in carrying thesewall forms around the corners I preferably make use 'of special interiorcorner studs '-10 and {exterior corner studs 11-, the inner corners ofthe interior studs being rabbeted and their edges beveled inwardly,while the outer corners of the exterior studs are rabbeted and theiredges beveled outwardly for receiving between them interior and exteriorwall panels l2, the edges of which are similarly rabbeted and beveled topermit them to be easily and quickly'placed in operative vposition andremoved or -stripped; when their fastening devices hereinafter describedare released. V

As previously explained, the lower ends are rabbeted and beveled to'seat snugly upon the upper rabbeted edges of their corresponding wallplates -3 where they are held in place by the bolts l' and keys eachstud being provided with a'plupanels 1'2 in and from their operativepositions.

spaced relation near their upper ends by concrete spacing sleeves 16-(Figure 15) extending across the intervening space -7-, and ofsubstantially the same length br width as the spacing blocks -'2, eachsleeve being provided with a central opening -c-' of angularcross-section'as shown more clearly in Fig. 15 for receiving a bolt -l7*of similar cross-sectionas shown in Fig. 14, said bolt having itsopposite ends extending through registering openings in the studs ofeach pair and provided with hook shaped slots for receiving'the pivotalpins of a pair of eccentriclevers 18, whereby when turned in onedirection, their eccentric faces will engage the adjacent faces ofthe'studs to hold them in operative position, or by releasing the leversthey may be withdrawn from their slots in the ends of Y the bolt l7 toenable the studs to be removed. y

The bolts '17' are provided with collars c rigid therewith for engagingthe outer ends of the sleeves 16 and inner faces of the outer studs 1land to thereby assist' in holding the'studs in properly spaced relationwhen the eccentric levers 18' are tightened; V

ripheral grooves --d-, as shownin Figure- 15, for receiving suitablereinforcing rods (not shown) forthe concrete and holding said. rods inplace as the concrete work progresses.

The inner stud sections for the outer wall of the cellar or first storyare preferablyerected first or before the erection of the outer studsfor the'same wall, andextend from 'fioorto ceiling, or from thefootingstrips -3 to the undersideof thefloor forms hereinafter described, saidstud sections being spaced a suitable distanceapart along the footingcourse of each side of the building for receiving between them panelsections 12- of the form'of suchrsize as maybe conveniently handled, itbeing understood that after the lower ends of the inner stud sections ofthe outer wall'have been secured in place to the footing .strips 3',they are properly plumbed, or brought 'into parallelism and temporarilyheld in this relation by stiffening members 23 applied thereto neartheirupper ends to 'remain'i'n place during the erection of the remainingsections of the outer wall of vthe and supporting gthe ,stiifenin membersame story; and: M OI LQ TQ we wh l i. may be a progre v ly erec ed b wen t e. nnerian outer form: sections for the same; wall.

j f'The formifor the column consists of, in

mama

devices of said brace to both the column formand stud section preferablyconsisting of pins which may be readily inserted through apertured partsof the connected members and quickly removed when desired.

When the inner stud sections 8 and -l0 of the outer wall forms and theupright plates 19 of the column form are erected in the mannerdescribed, the girder forms are next placed in position upon the upperends of said stud sections and plates, each girder form consisting of apair of opposed sheet metal channel plates 22 arranged endwisevertically with their channels facing each other and-in spaced relationtransversely for receiving and supporting a pair of inner wood sections2T which are also arranged edgewise vertically in transversely spacedrelation against the inner faces of the channel sections -2Q- and areprovided at their upper ends with out-turned flanges 28 resting upon theupper edges of said channel sections, the space between the lower edgesof the wood sections being filled in by an additional wood plate 29which is held in place by a button -15 similar to those previouslydescribed for holding the wall panels in place, except that thesebuttons are pivoted to the underside of the,

plate -29- to swing in a horizontal plane into and out of engagementwith suitable keepers 30 on the lower edges of the channel plates 22 asshown more clearly in Figures 2 and 16.

As previously intimated, portions of the girder plates 22 rest uponseats on the inner faces of the longer plates 19 near the upper endsthereof, and are additionally held in place upon the column forms byclips 31- and keys '32- which are passed through registering aperturesin clips and adjacent portions of the longer plates 19 as shown inFigure 16.

The outer ends of the girder plates 22 are supported upon the upper endof one of the stud sections 8, which is directly opposite the columnforms and may be additionally held in place by clips on said studsection.

By assembling the parts of the girder in the manner shown formsalengthwise channel'therein openat the top and communicating with thespace between the plates of the column form and also with the space between the inner and outer stud sections of the wall forms for receivingthe concrete for the walls and girders.

The joist forms extend from opposite sides of the girder forms to theinner studs 8 of the outer Wall forms at right angles to the girder andin parallel spaced relation corresponding to the spacing of said studsections, each joist consisting preferably of a pair of reverselyarranged sheet; metal T- pieces 33-, or what is commonly known as metallumber, having their vertical flanges overlapping and secured to eachother and provided at suitable intervals with pendant bolts or threadedstuds 34 for receiving buttons l5 and retaining nuts 14 therefor theupper ends of the metal pieces 33 being capped by a wood strip or filler35 as shown more clearly'in Figure 19.

The metal strips of each joist form are secured at one end to the girderplates 22- by clips 31- and tapered pins 2 which are passed throughregistering apertures in the clips and adjacent end of the joistsections 33-. The other end of each of the joist sections 3 is supportededgewise upon the upper end of the adjacent stud section 8 and isclamped thereto by a tapered key 5 similar to that previously describedfor locking the lower ends of the studs to the footing strips 3, exceptthat it is passed through apertured lugs 37- and -38," on the adja centportions of the metal section 33 and stud -8-, respectively, as shown inFigures 16 and 20.

The end of each joist form which is secured to one of the inner studsections of the outer wall form is provided with a removable extension36 having hookshaped attaching members for interlocking engagement withpins et0 on the sides of the metal sections -33 the outer end face ofthe extension 36- being substantially coincident with the inner face ofthe adjacent stud when the joist form is assembled thereon to form asubstantially unbroken surface along the inner face of said stud sectionfrom the footing course to the floor, while the upper face of the sameex tension is disposed in a horizontal plane substantially coincidentwith that of the upper face of the filling piece 35 and is adapted tooverlap upon said filling piece and also upon the upper face of theadjacent-end of the metal strip 33- to form a liquid tight jointtherewith. The adjacent end faces of the main body of the strip 33 andextension 36 are beveled downwardly and outwardly, but are normally heldtogether when the parts are assembled by hook-shaped members 39--- onthe extension 36 adapted to interlock with pins -4l0 on opposite sidesof the adjacent end of the metal strip 33, as shown more clearly inFigures 16, 17 and 18.

The only object in providing the joist form with a separable end section36 is to enable these forms to be more easily stripped from the concreteafter the latter is set.

It will be seen from the foregoing description that the floor formsaresupported entirely by the column forms and inner stud sections 8- and10-- of the outer wall forms independently of the outer stud sections 9and 1i, and that these inner stud sections 8- and -10-, together withthe inner footing strips -3, girder forms and joist forms constitute askeleton frame for receiving and supporting the inner panels of the wallforms and also the panels of the floor forms.

The outer stud sections 9-- and --1l-- of the outer wall form arepreferably erected directly opposite the inner stud sections -8 and -10-after the latter have been installed and properly braced, and in factthe installation of these outer stud sections may be deferred until thefloor forms are placed in operative position, and while it may bepreferable to complete the erection of the forms for one story at atime, it is evident that the forms for the several stories, includingthe floor forms, may be erected before the concreteis poured into the intervening spaces.

and -10 which face each other, are rabbeted and beveled inwardly to formstop flanges for limiting the inward movement of the panel sections l2to approximately the vertical plane of the footing strip 3- and studsections -8- so that the outer faces of those parts when assembled willlie in substantially the same vertical plane where they are held byturning thebuttons ---]r5- across the inner faces of the adjacentportions of the panels as shown more clearly in Figure 4.

These panel sections are preferably made up as units of such size as maybe conveniently handled and preferably of a width corresponding to thedistance between the stud sections, while the vertical height of eachpanel is equalto substantially half the height of the story from floorto ceiling, thus requiring in this instance two panels one upon theother to fill each space-between the stud sections, the lower edge ofthe loweu most panel and upright side edges of both panels being alsorabbeted and beveledto cause them to fit snugly againstthecorrespoii'ding rabbeted'edges of the footing strip --3 and studsections, and to thereby form substantially liquid tight joints. Theadjacent meeting edges of'both panel sections, which are arranged oneupon the other, are also rabbeted and beveled for the same purposeandare held against inward displace ment one upon the other by buttons 15--siiriilar to those previously described. The

outer footing strip '3 and edges of the outer stud sections 9- and 1 1,which face each other, are also rabbeted and beveled outwardly toreceive panels '12- which are similar to the inner panels except thatthey extend above the level of the lower surface of the floor, but arepreferably divided to form two panels for each space between the studsections, the lower edgeof the may be removed by outward displacementwhen stripping the forms.

The panel sections, as 4E0, for the floor forms are of substantially thesame area as the spaces between the joists and between the joist andouter walls, and are provided with substant ally flat upper surfaces,the

edges thereofadjacent the joists being supported by buttons '15- whichare mounted upon the bolts -3l and held in place by the nuts -14, asshown more clearly in Figure 19, in which they are shown as providedwith ledges -41 extending under the adjacent edge of the filler strip35-' to form a liquid tight jointtherewith, while theedges adjacent theouter wallsare preferably supported upon the upper ends of theinner'stud sections 8- and 10- and also upon theupper edges of the innerpanel sections 12 being placed in position from below and held in placeby the buttons The edges of the floor panel sections ad jacent thegirders may be secured in any suitable manner to said glTClGIS to formliquid tight joints therewith.

The forms for the remaining stories may be successively erected infiamanner'which is practically a repetition of that previously describedfor the first story, except that'the" floor forms constitute a supportfor the' spacing blocks 2' instead of the concrete footing course Thatis'theconcrete spacmg blocks 2 ceiving and supporting inner= footingstrips 3- similar to those previously described as resting 'upon theconcrete footing course a re supported upon the upper flat facesofthe'fioor forms for re determine the thickness of the wallywhile otherportions extend horizontally to determine the thickness oft-he floor.

The inner footing strips -3 rest upon the horizontally extendingportions, under which COHClltlOIlS the outer panels for the outer wallmay he built up continuously one uponthe partition walhthe horizontalportions determining the thickness of the floor and correspond inthickness with the horizontally extending portions of the spacingmembers 2- for the outer walls, and serve to support additional footingstrips 7 3 for the partition forms. 5 ,1

These footing strips, like those previously described as resting uponthe footingcourse l, aresecured to the separator blocks by' bolts 4. andwedge keys -5, which may be readily removed when stripping the forms.The partition forms are similar to the outer wall forms in that they arecom posed of inner upright studs '8 and outer upright studs -9-, bothofwhich are secured in transversely spaced relation to the footing strips3- and rise to points in proximity to the ceiling of the next floor forreceiving and supporting intervening panels- 1isimilar to thosepreviously described.

It beam ceilings are iequired,-tli e joist 33- will simply be loweredwith a correspouding lowering of the filler plates in which case theadjacent sides of the panel sections, as 4CO, will be extendeddownwardly a corresponding distance to bring the ledges l1- against *theunderside of said filler plates as shown at the upper floor of Figure 1.

In stripping the various parts of the building form after the concretefor the walls. columns. floors and partitions have set. the order ofassembly of those parts will be reversed. the panel sections being firstremoved, then the floor sections. following which the stiffener-s andbraces, and then the stud forms and column forms may be rei moved, allof which may be re-used in the erection of forms for other buildings.
